Device for bending winding segments to form a winding

Abstract

A device for bending a plurality of winding segments to form a winding of a winding carrier of an electric machine is provided. The device includes: a holding device designed for holding in place the winding carrier in which the winding segments are arranged; a main bending device, including a number of main locking elements, which point towards the holding device, are arranged along first sections of a circumferential line and are designed to lock exposed end sections of first winding segments; and a partial bending device, including a number of partial locking elements, which point towards the holding device, are arranged along second sections of the circumferential line and are designed to lock exposed end sections of second winding segments. The holding device on the one hand and the main bending device and the partial bending device on the other hand are rotatable relative to each other.

What is claimed is: 
     
       1. An apparatus for bending a plurality of winding segments for forming a winding of a winding support of an electrical machine, the apparatus comprising:
 a main bending device comprising a number of main locking elements that face a holding device and are arranged along first sections of a circumferential line, the circumferential line runs around an axis, the main locking elements are designed to lock exposed end sections of first winding segments and to bend the first winding segments at a first bending region, the holding device holding the winding support in which winding segments are arranged; 
 a partial bending device comprising a number of partial locking elements that face the holding device and are arranged along second sections of the circumferential line and are designed to lock exposed end sections of second winding segments and to bend the second winding segments at a second bending region, the circumferential line extending through the number of main locking elements and the number of partial locking elements; 
 wherein the holding device rotates in relation to the main bending device and the partial bending device; 
 wherein the first winding segments at the first bending region are bent by a bending angle, and the second winding segments at the second bending region are bent by the bending angle; 
 wherein the first winding segments at the first bending region are bent at a first bending length at the bending angle being between the winding support and the main bending device; and 
 wherein the second winding segments at the second bending region are bent at a second bending length at the bending angle being between the winding support and the partial bending device; 
 wherein the first bending length and the second bending length are different. 
 
     
     
       2. The apparatus of  claim 1 , wherein the holding device and the main bending device are designed such that the holding device and the main bending device can rotate bidirectionally in relation to one another. 
     
     
       3. The apparatus of  claim 1 , wherein the holding device and the partial bending device are designed such that the holding device and the main bending device can rotate unidirectionally in relation to one another. 
     
     
       4. The apparatus of  claim 1 , wherein the circumferential line is in a shape of an ellipse, wherein the axis passes through a center of the ellipse. 
     
     
       5. The apparatus of  claim 1 , wherein the circumferential line is in a shape of a circle, wherein the axis passes through a center of the circle. 
     
     
       6. The apparatus of  claim 1 , wherein the main locking elements and/or partial locking elements are in a form of gripping elements or in a form of recesses into which end sections of the winding segments can be inserted such that the end sections of the winding segments fit. 
     
     
       7. The apparatus of  claim 1 , further comprising a rotary drive device designed to rotate the holding device, the main bending device and/or the partial bending device in relation to one another about the axis. 
     
     
       8. The apparatus of  claim 1 , further comprising a linear drive device designed to move the holding device, the main bending device and/or the partial bending device independently of one another in a direction of the axis.
